Tianjin Petrochemical Company (Steam Flow Fixed-point Laboratory, China Academy of Metrology)

Project Name: Standard Device for Adjustable Dryness Steam (Gas) Flow

The main technical parameters: Sonic nozzle method device expansion uncertainty: 0.5% (Sonic nozzle uncertainty 0.2%) (K = 2)
Mass method device expansion uncertainty: 0.05% (K = 2)

Test pipeline range: DN20 ~ DN250

Flow range: air 1-10000Nm3 / h; steam 0-4T / h

Project description: This project is a comprehensive set of domestic gas and steam researches built by Sinopec and China Metrology Institute
And experimental devices, all designed and constructed by our company. The complete device consists of two parts, one of which is a standard device for compressed air gas flow
The test pipe section is DN25-DN200. The test pressure can reach 0.7MPa. The flow can reach 10000m3 / h. The other part is the superheated steam test device.
This device is multiplexed with the DN25-DN100 diameter of the compressed air device. Flow through the valve. The steam part can not only carry out the steam flow meter
Real-flow calibration, and can also carry out research on the quality and grade of steam. This project belongs to the national key scientific research project.
